The Joliet Diocese readily admitted that David Rudofski was sexually abused during his first confession at St. Mary Catholic Church in Mokena. It offered him an in-person apology from the bishop and more than six times his annual salary in the hope of putting a quick, quiet end to yet another ugly incident involving a priest.

But Rudofski wanted more than money.

The south suburban electrician wanted the diocese to truly pay for its repeated and, oftentimes, willful mishandling of sexual abuse cases involving clergy — and he insisted on a currency far more precious to the church than money. He demanded that the diocese settle its debt by turning over the secret archives it maintained on abusive priests and making them available for public consumption.

"What was I supposed to do? Take the money and run?" Rudofski said. "How would that help anybody else? If people don't know how this was allowed to happen for decades, they can't prevent it from happening again."

The diocese, however, fought Rudofski's efforts for more than a year before agreeing to turn over the personnel files of 16 of the 34 priests with substantiated allegations against them. It also issued a news release adding his alleged abuser, the Rev. James Burnett, to its still-growing list of accused clergy.

The files, which Rudofski's attorney shared with the Tribune after redacting the names of other victims, contain more than 7,000 records detailing how the diocese purposefully shielded priests, misled parishioners and left children unprotected for more than a half-century. They also raise new questions about whether the church has been forthcoming about the number of local priests involved in the scandal and the percentage of clergy confronted with credible claims.

Though the Joliet Diocese's botched handling of pedophile priests has been well-documented in recent years, the records offer the most complete portrait of the ineptitude and indifference that greeted the allegations almost since the religious district's inception in 1948. The errors span more than six decades and involved three bishops, 91 places of worship and more than 100 victims.

Researchers and Roman Catholic Church officials have previously said that about 4 percent of priests nationally committed an act of sexual abuse against a minor between 1950 and 2002, with church officials claiming the rate of abusers within the priesthood is no different from that among other professions.

However, the files show that the Joliet Diocese — which includes parishes in DuPage, Ford, Grundy, Iroquois, Kankakee, Kendall and Will counties — had double or triple that percentage in the 1980s. In 1983, for example, more than 13 percent of priests serving in the diocese would later have credible abuse allegations leveled against them.
